These Rotor Q-Rings feature a subtle yet efficient 10% ovality which can be user adjusted to take advantage of your full pedal stroke potential. These rings are available as inner rings (black or red), in various sizes & BCD fitments.

Easy to fit and adjust, makes a difference
I use a single ring on a hill climb bike. The Rotor took about 20 minutes to fit and no adjustments were needed on the front mech. On the road, its different, looking down the front mech looks very strange and on my favourite training hill it was quick but there is a learning curve - the bumph says give it 10 hours and I'm nowhere near that. It feels like a tailwind and I suspect its of more benefit to the pedal mashers than the spinners. I went for the Rotor as a conservative choice and I wonder if the Osymetric is better?

Great upgrade
Got the inner and outer rings. Only used the default settings so far. The inner ring made a massive difference to long steep climbs. The outer one not so much difference in general riding - but maybe I haven't got that one adjusted correctly as yet. Need to try some other settings as suggested in the instructions so maybe that will also help as well.

Great product
I have the Rotor chainset and have been using it for some time now. At first it took some getting used to but once you have adjusted you will love using them. I have posted some PB's using this chainset. Highly recommended.

Answer:

I can confirm that the Red one is the correct inner ring and is a Q ring as well but the Asymmetry is not as pronounced on the inner. The black one shown is an outer and we will get the site updated as soon as possible.I hope this helps,
